Transformers do not convert AC to DC. They are designed to adjust the voltage of alternating current (AC), either stepping it up or down, but they do not alter the nature of the current. Transformers work based on electromagnetic induction, which only functions with AC, so they cannot process direct current (DC).
AC to DC Conversion
To convert AC to DC, a rectifier is used. A rectifier only allows current to flow in one direction, effectively converting AC to DC. While transformers can change the voltage of AC, they cannot change it from alternating to direct current.
Role of Transformers
- Voltage Regulation: Transformers adjust voltage levels in AC circuits.
- Isolation: They provide electrical isolation between different parts of a circuit.
- Power Distribution: Vital for AC power transmission, but not involved in converting AC to DC.
In summary, while transformers play a crucial role in handling AC power, the conversion to DC requires a rectifier in addition to the transformer.
